Why convert images to WebP?

WebP files are typically 25-35% smaller than JPG or PNG at the same visual quality, and they support transparency. Smaller images mean faster pages and better Core Web Vitals scores, which is why PageSpeed recommends modern image formats.

How to convert to WebP

Upload a JPG or PNG image.
Set the quality with the slider (75-85 is a good start).
Compare the original and WebP file sizes.
Download the WebP file and use it on your site.
